Cisco QSFP-100G-ER4L-S Compatible 100GBASE-ER4 QSFP28 1310nm 40km OS2 DOM Duplex LC SMF Optical Transceiver Module |
|
When a 100G link must stretch beyond 10 kilometers, the 100GBASE-ER4 QSFP28 module takes over. It pushes four LAN-WDM lanes up to 40 kilometers over OS2 single-mode fiber on engineered links, using a high-sensitivity APD receiver, and it is fully compatible with Cisco QSFP-100G-ER4L-S ports. The transmitter multiplexes four 25G wavelengths in the 1310nm window onto one fiber pair through a duplex LC interface, while the APD receiver recovers weak signals at extended distance. Links up to roughly 30km typically run without host FEC, and full 40km reaches are achieved with FEC enabled on the host platform. DOM diagnostics report per-lane power, temperature and voltage for proactive maintenance across metro deployments. Related 100G QSFP28 products: |
